9.6. ENFERMIDADE MACULAR
DEXENERACIÓN MACULAR ASOCIADA A IDADE
Esta condición é moi común en persoas adultas. Está danada ou destruída a zona central da retina. Mantense a visión periférica, pero xa que se usan principalmente bastóns a visión pode ser borrosa e sen cor. Non ven a parte central do campo visual polo que non poden ler e con frecuencia non visualizan as caras das persoas coas que falan.
Hai dous tipos principais. A dexeneración macular seca e o resultado da baixa irrigación sanguínea na retina. Desenvólvese lentamente pero non ten tratamento por agora. A dexeneración macular húmida pode ocorrer rapidamente. A causa é a proliferación de vasos sanguíneos debaixo da retina.
O tratamento para frenar o crecemento dos vasos sanguíneos ou a ciruxía para extraer ditos vasos, non reverte o proceso pero evita que empeore.
Age-related macular degeneration (AMD)
This eye condition is quite common in older people. The central region of the retina is damaged or destroyed. People keep their peripheral vision, but as that uses mainly rods vision can become blurred and not in colour. People cannot see in clear focus and they can’t see the middle of their field of vision which means they can’t read and they often can’t see the faces of the people they are talking to.
There are two main types. Dry AMD is the result of poor blood supply to the retina. It develops slowly but can’t be treated at the moment. Wet AMD can develop very fast. It is caused when abnormal blood vessels grow under the retina. It can be treated by drugs which stop the blood vessels growing and sometimes by surgery to remove them. Treatment doesn’t usually reverse the damage but it stops it getting worse.
